Stormwater Pollution

Only stormwater is allowed to enter into the storm drain. The cities and County of San Mateo protect stormwater from pollution by inspecting industrial and commercial businesses, managing construction and redevelopment activities, and providing education and outreach to businesses and residents of San Mateo County. Help protect our community and waterways by reporting stormwater pollution when you see it.
